KuCoin blocked your account or funds — what to do
After its 2024 DOJ settlement KuCoin tightened KYC/AML sharply: legacy accounts without full verification get restricted, deposits with a risky trail get frozen, withdrawals go into "security review." Most cases are procedural but demand proper documentation.
Why accounts get frozen
Legacy account without KYC
Accounts created before mandatory verification are restricted until full KYC.
Deposit AML screening
An incoming transfer with a high-risk trail — standard freeze pending explanation.
Jurisdiction restrictions
KuCoin exited several jurisdictions; a KYC/geo mismatch is a trigger.
P2P complaints
Fiat from counterparties with stolen funds — frozen upon complaint.
What to do — step by step
- Complete full KYC with your own documents — nothing moves without it.
- Record all correspondence and exact requirements.
- Get an AML report on your addresses before submitting explanations.
- Build a chronological Source of Funds in English.
- Silence beyond 3 weeks — a written compliance escalation with the case number.
What NOT to do
- Do not pass KYC with someone else's documents — an irreversible refusal.
- Do not use a VPN to "change jurisdiction" during review — geo-jumps read as evasion.
What Onyx does in your case
- Forensic report on your addresses (Chainalysis/TRM class): what exactly triggered the flag and your real distance from the risk cluster.
- Source of Funds dossier — a chronological reconstruction of your capital with documents, in the format compliance actually reads.
- Communication with KuCoin compliance — one verified position instead of ticket chaos.
Frequently asked questions
KuCoin demands KYC on an old account with funds. Legal?
Yes: after settling with US regulators the platform must verify everyone. Without KYC the funds stay frozen — compliance, not negotiation.
How long is the withdrawal security review?
1-2 days to several weeks. AML cases with Source of Funds requests — up to 90 days.
KuCoin no longer serves my jurisdiction. Funds gone?
No: there is normally a withdrawal window after KYC. Follow the official procedure rather than waiting.
